To remove dogmatic elements from something; to make less dogmatic or rigid in doctrine.
From de- (reversal) + dogmatize (to state as dogma/doctrine). Dogma comes from Greek 'dogma,' meaning 'opinion' or 'tenet.' The term appears in philosophical texts from the 1800s onward.
Religious reformers and philosophers used 'dedogmatize' to describe making institutions more flexible and open-minded—removing the stubborn 'believe this or else' attitude. Vatican II essentially tried to dedogmatize Catholicism!
